DYEING-lVIACEINE.

Specification of Letters Patent.

Patented Aug. 24;, 1920.

Application filed January 9, 1920. Serial No. 350,273.

To all whom it may concern Be it known that I, Eazrn SoriNUnRnN- BERGER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Dyeing-Machines, of which the following is a specification.

In treating skeins with liquids, notably in dyeing, the hand operation consists in shifting the sticks on which the skeins are hung and which rest on the sides of the liquor vat one after another along the vat so as to sweep the skeins through the liquor, thus both to cause the skeins to be well permeated by the liquor and keep the latter well mixed; when this shifting has been done several times, first one way and then the other, the operators change the skeins so as to immerse the part of each which was last exposed or out of the liquor. This manual operation is a slow, tedious and expensive one, and the object of the invention is therefore to provide a machine for accomplishing this work in which these objections will be overcome, and while the principal object of attaining an effective sweep of each skein through the liquor will be accomplished, with consequent good permeation thereof by and an effective stirring of the liquor of treatment, the skeins will be saved any injurious frictional contact with parts of the apparatus or with each other, which is a fault characterizing machines heretofore devised for doing this work.

In the drawings,

Figure 1 is a side elevation, partly broken away, of the apparatus;

Fig. 2 is a plan;

Fig. 3 is an end elevation, the vats appearing in section; 0

ig. 4 is a plan of the means forcausing the sweep of the skeins through the liquor, with the main frame which supports it shown in horizontal section;

Fig. 5 is a sectional detail of said means; and

Figs. 6, '7 and 8 are'views illustrating three different positions of a skein.

In the present instance there are two vats a (4 shown, the means for supporting and moving the skeins being set between and arranged to overhang them.

A hydraulic ram 6 is shown with its upper or moving member I) capped by a plate 0 which supports a horizontal frame comprising the horizontal rails d and the cross-pieces e. The ram is adapted for raising and lowering the frame and the mechanism carried thereby when a treatment has been effected and the treated skeins are to be removed and replaced by those to be treated. In transverse bearings f on this frame are journaled cross-shafts g each having a wormand-worm-wheel connection It with a longitudinal shaft 2' journaled in the crosspiece 6 of the frame, which shaft 2' has a gear jto mesh with a suitably driven gear when the frame is lowered to position for a treatment of the skeins (Fig. 1). On the ends of the shafts g are secured, as by set screws Z, the socketed ends of the skein carrying reels The gear-connections 171, are preferably such that adjoining reels rotate reversely to each other, though this is not indispensable.

On the frame (5-6 is arranged to slide another frame including the longitudinal rails n and cross-p'eces 0 in the preferred construction the rails d have horizontal slots d in which the cross-pieces of frame n-0 slide .in frame (Z@ and carrying a crank disk '10 which is connected with the frame 72-0 by the pitman o.

Projecting laterally from rails 11 of frame n0 are arms 0 which carry rails w, and projecting from these rails are sticks arranged in two sets a: 3 each stick in being adapted to extend through a skein and each stick y to project between two adjoining skeins. It will be better to form each rail 20 in two horizontally separate sections hinged together and mount one set of the sticks on the lower or fixed section and the other 011 the hinged section. In the present instance when the frame n0 is in its midposition the lower row of sticks register vertically with the respective reels m, which are arranged at equal intervals, and the upper row register with the spaces between the reels; the traverse of the frame may have any desired extent, in the present instance being somewhat more than the centerto-center spacing of the reels.

It will be understood that when the skeins are being treated the rotation of shaft 2' transmits rotation, through gearing h, to

llO

the several shafts g and hence to the reels, so as to cause movement of each skein on its reel after the manner of a belt on a pulley, thus to progressively immerse it in the liquor; and that at the same time frame n0 is being reciprocated so that the sticks 03, y, effect a'sweeping of the skeins through the liquor first all one way and then all the other way, whereby the liquor is not only kept'stirred but is made to thoroughly and uniformly permeate the strands of the skeins. By arranging sticks 03 to penetrate the skeins each stretch or side of a skein is kept away from the opposite stretch or side, so that they do not become mattedtogether and uniformity of thetreatment is thus promoted; the sticks y, which alternate with the skeins, serve'to shift the relatively rearward stretch of each skein forward (in the direction in which the sticks .71 are displacing the relatively forward stretches of the skeins) so that it will not be interfered with by the skein next behind.

In a well-known machine for performing this work the skeins are hung on reels arranged. eccentrically of horizontally rotating members, in which case if the speed of rotation is fast enough to obtain adequate stirring of the liquor ane good permeation of the skeins as they are swept through the same the skeins become unduly worn by the friction of the reels (particularly at their end heads or flanges) therewith." In my construction the rotary movement of the reels and the sweeping movement of the skeinsare not nterdependent, because their speed ratio may be changedby changing the gearing connecting the rotary reel and the reciprocating frame 7P0, and so the rotary movement of the reels may be as slow as is expedient and the sweeping movement of the skeins as fast as necessary in order on the one hand to progressively subject each skein to the liquor without undue fric tional wear by the reel and on the other to insure good agitation of the liquor and thorough'permeat-ion of the skeins.

.I Vhen the machine is unloaded and reloaded, at which time the ram has been made to lift the skeins clear of the liquor, the frame n-0 will .usually be first set at the mid-position of its traverse so as to bring the sticks .13 in the most convenient relation to the reels, and at that time the rail carrying the sticks y may be swung up on its hinges soas to be out of the way and avoid any possibility of some of the skeins being slipped over the sticks 7 Thesweeping of the skeins through the liquor of treatment is accomplished according to my invention so that the lower or immersed parts of the pendent skeins are trailed through the liquor by the displacing devices 00, g which so far as I am aware is new in machines of this class; inasmuch as skein )endent in the liquor and means heretofore only characterized the manual operation already described. 7
